Hi blinder. I'm assuming you're looking for the equations to calculate the work done on an ideal gas when undergoing the various processes you've listed. A polytropic process is the most general, so we can start with that. Also, the equations should work just as well for compression or expansion (work in or out of the gas).

As you must already know PV^n = constant is a polytropic process. If you compress a gas, the work done is the integral of PdV. If we integrate that for a polytropic process you end up with:
